Hi guys, a little help required today! My Mutt Fat Sabbath battery decided it would pack in this week, so I went and bought another online, following the specs that I had found from different websites. Turns out, the specs were wrong (and I wasn't in the same place as the bike to measure), so the new battery is too large. I have bought a Yuasa YTX12-BS (LxWxH 150x87x130) and it annoyingly doesn't fit, and the bike came with a shitty Chinese battery which is already dead less than a year on (Shenchi BTX9A-BS). I can't seem to find those of the correct size (the Shenchi is LxWxH 130x70x130), so any recommendations would be grand. 12v 10Ah would be best. (Additional question, how much of an increase can be made with Ah?) Thanks everyone!
